ATI knows that it will take serious muscle to go against Fermi GF100 based cards, but it still has a few more cards to play. Whenever Nvidia realistically launches its new GF100 40nm based card, ATI should have its kicker chip around the corner.

They did this with 4890, the first gigahertz card and got quite a lot of attention so you can easily expect a new 58x0 card with pretty much the same agenda. We don’t know any specs at this time, but we know that the company is working on such a card.

Before this card comes out you can expect huge price cuts on Radeon HD 58x0 parts, but this will only happen when ATI's sales start to suffer due to GF100 Fermi launch. Of course, this is yet to happen.
